I've also had this happen 2 times today. After having emphatic display lyrics for an even longer period of time after the horizontal display ceases to work....It hangs the display of the rio all together with the buttons on the rio also not working. The remote still works however. Just wanted to let you know. Actually i think it happened 3 times. Figures I would have all the wierd problems seeing as i have so many lyricized songs:) Thanks _yn0t, your an awesome programmer and give great support.
